POSTER: computer news   ||   RV770, RV740 AND RV710 VIDEO CHIP	DATE:2008-02-16
The new generation AMD graphical solutions will appear at the end of the second quarter 2008. Let us  examine the early forecast. RV770 - > 480 stream processors, 32 textural blocks, 16   rop blocks , 256- bit memory bus; RV740 - > 240 stream processors, 24 textural blocks, 12 rop blocks , 256- bit memory bus; RV710 - > 40 stream processors, 8 textural blocks, 4 rop blocks , 128- bit memory bus. Those chips will be produced on 55 nm technology. the middle class solution RV740 will propose the 256- bit memory bus. The number of textural blocks will be doubled in comparison with previous generation products  . Let us examine the characteristics of video card on base of these chips: Radeon HD 4870 x2 (2 x RV770) - > frequency  1050/3600 MHz, 1 Gb or 2 Gb Gddr-5, TDP=250 W, $499; Radeon HD 4870 (RV770) - > frequency 1050/4400 MHz, 1 Gb Gddr-5, TDP=150 W, $299; Radeon HD 4850 (RV770) - > frequency 850/3600 MHz, 512 mb Gddr-5, TDP=120 W, $249; Radeon HD 4670 (RV740) - > frequency 1000/2400 MHz, 512 mb Gddr-4, TDP=100 W, $149; Radeon HD 4650 (RV740) - > frequency 800/2000 MHz, 256 mb Gddr-4, TDP=80 W, $129; Radeon HD 4470 (RV710) - > frequency 900/1600 MHz, 256 mb Gddr-3, TDP=50 W, $79; Radeon HD 4450 (RV710) - > frequency 700/1000 MHz, 128 mb Gddr-2, TDP=30 W, $59. TDP value are given in the worst conditions. In the quiescent conditions the energy-saving technology PowerPlay new generation will allow to reduce the energy consumption level to 10-25 W even for high end video card. Related Products :
